- Int( <expression>, <variable>, <lower bound.>, <upper bound.> ).
- Description: the function calculate the integral of <expression> with the respect of the <variable> on the real interval defined by <lower bound> et <upper bound>. The calculation is done using the SIMPSON method two times accelerated with the ROMBERG method, <expression> is supposed definite and enough regular on the integration interval.
- Exemple(s): Int(exp(sin(u)),u,0,1) gives 1.63187 (Maple gives 1.631869608).
